Sometimes, you don’t need words but a simple smile. Although I am using the SLR-shaped OM-D, I try to use the LCD screen instead of peering into the viewfinder. Since the camera is quite light, I hold it like a compact camera in situations such as these. That way, the subject can see my face and smile back
The Nine Emperor Gods Festival is one of the most colourful Chinese festivals. As such, few people attempt black and white shots. Next time you are there, try some alternative shots in native black and white (if your camera supports this mode) or desaturate the colours later.
